Ma and Wang proposed using energy piles to store solar thermal energy underground in summer, which can be retrieved later to meet the heat demands in winter, as schematically illustrated in Fig. 1. A mathematical model of the coupled energy pile-solar collector system was developed, and a parametric study was carried out.
Quantitatively, the daily average rate of energy storage per unit pile length reaches about 200 W/m for the case in saturated soil with turbulent flowrate and high-level radiation. This is almost 4 times that in the dry soil. Under low-level radiation, it is about 60 W/m.
In addition, the model domain of the energy pile-soil system has limited dimensions and thus only five cycles of energy storage were maintained for each test. These factors affect the results quantitatively, while they should not invalidate the fair comparison between different tests.
This was determined to avoid oversizing the pile diameter. It should be noted that a realistic diameter of 20 mm was adopted for the thermal loop embedded inside the energy pile.
Energy piles, which embed thermal loops into the pile body, have been used as heat exchangers in ground source heat pump systems to replace traditional boreholes. Therefore, it is proposed to store solar thermal energy underground via energy piles.
